Do text messages take up space in iPhone storage?

Haha Faisal, your source is entertaining. However, they are in fact stored on your phone. They take up a very small amount of space, though, unless you're a heavy texter and send/receive a lot of attachments.My suggestion would be to either delete some conversations or get the info you really need backed up to a computer or iCloud and do a reset on your iPhone to get rid of any unnecessary information that may be taking up space.

Yes, messages that you haven't deleted take up space on your phone. However, the space they use is really, really small compared to the capacity of the phone. You can store tens of thousands of text messages on the phone and still hardly make a dent in its capacity.

Chances are that something else is taking up space. Some apps store a lot of data on the phone, and some apps are really big themselves (especially if they contain lots of data, like tons of text and videos and stuff). Music takes up space, more than messages but less than videos. Videos take up tons of space. Photos take up slightly less space than music. So look for music, videos, photos, or apps that you can delete. Apps and music can easily be deleted if you bought them from Apple, because you can always reinstall or redownload them if you want.
